Your argument is flawed in a twisted little way.
No one is actively taking your gasoline driven car away. If you really need it, keep it. But for the largest part of the population, it might make sense to drive an electric car most of the year, and only for the few long trips into sparsely populated regions, they can rent a gasoline powered one.
Your argument is akin to arguing that cars are not usable for anybody, because there are some people living on small islands who need a boat to get somewhere else, or because once in a while, you need to go by airplane, because it would take too long to drive from New York City to Seattle. Yes, there are special cases, when a car is not a good solution. For those cases, we have other solutions. But that doesn't mean that we have to abandon cars. People living on small islands will not be frequent car customers. So what?
The same can be said for electric cars. Yes, there are special cases where they aren't a good solution. But for most people in most cases, they are. And for special needs, there are special transportation means you can use -- be it a gasoline powered car, a train, an airplane, a boat or a bicycle. It doesn't mean that you have to own all of them.
